Causes of insomnia the night before menstruation

Premenstrual insomnia may be related to hormonal changes. During the menstrual cycle, levels of estrogen and progesterone fluctuate, especially during the luteal phase before menstruation, when progesterone levels rise, potentially causing various physical and psychological changes. Progesterone affects body temperature regulation, which may cause increased feelings of warmth and disrupt sleep. At the same time, it may also influence neurotransmitters in the brain, such as serotonin, which are associated with emotional stability and sleep quality. Additionally, as the menstrual cycle approaches its end, levels of prostaglandins in the body may increase, potentially causing pain, such as abdominal cramps or breast tenderness, and these discomforts may also interfere with sleep. Stress and emotional fluctuations, such as symptoms of premenstrual syndrome (PMS), including anxiety, depression, or mood instability, are also common factors contributing to premenstrual insomnia. If insomnia severely affects quality of life, it is important to seek medical advice promptly.
